PERIKUTATION HASP-LOCK.

Specification of Letters Patent.

Patented April 27, 1909.

Application filed June 17, 1908. Serial No. 439,015.

To all whom it may concern:

Be it known that we, JOHN W. MCFALL and LoUis C. G'RIESS, citizens ofthe United States, residing at Evansville, county of Vanderburg, andState of Indiana, have invented certain new and useful Impro vements inPermutation. Hasp-Locks, of which the following is a specification.

Our invention relates to permutation hasp looks.

The object of the present invention is the provision of a simple,inexpensive, durable, and secure permutation hasp lock which will beparticularly designed for use on trunks, boxes, or other similarreceptacles although susceptible of use in other connections whereby thenecessity for using a key will be done away with and the lock may besecured or opened with rapidity and ease by one knowing the combinationbut will be diilicult to open by unauthorized persons and which will beof such improved construction that the dials will be housed so that theywill not be damaged by being struck by another trunk or other object.

The invention is set forth fully herein after and the novel featuresrecited in the appended claims.

In the accompanying drawings:Figure 1 is a front view of the look asused on a trunk or box; Fig. 2, a rear elevation of the keeper and aportion of the hasp," Fig. 3, a front view of the keeper and partscarried thereby Fig. 4, a rear view of the hasp and )arts carriedthereby; Fig. 5, a vertica section through the keeper, the hasp, and thelock; and Figs. 6 and 7, inside face views of the plates carried by thekeeper.

The hasp isshown at 1 and the keeper at 2. When the lock is used on atrunk the hasp will be hinged to the trunk and the keeper 2 fixed to thelid thereof and secured thereto by rivets or other fastenings in anywell known manner. The keeper has a concavity 3 Whose wall is relativelyhigh for a purpose set forth hereinafter. 'ihe keeper has a circularaperture and sets of indentations or notches 5. Disposed back of thekeeper is a plate 6 having an aperture provided with notches 7 extendingoutwardly from its margin. Back of the plate 6 is another plate 8 havingan aperture )rovided with notches 9 extending outwardly from its margin.The plates 6 and 8 are separated or spaced from each other by thespacing washers 1O 1. and the plate 6 is spaced from thekeeperby l thewashers 1]. Suitable fastcnings 12 secure the washers and the plates 6and S to the keeper. The hasp has a part 13 adapted to fit in theconcavity 3 and is provided with an aperture 1% from the margin of whichlugs 15 project inwardly.

The numeral 16 designates a tumbler adapted to turn in the opening letand provided with a groove 17 which receives the lugs 15 whereby saidtumbler is prevented from coming out of place. The tumbler 16 isprovided with projections 18 positioned and shaped like the notches 5.Rotatablc within the tumbler 16 is another tumbler 19 which has a groove20 in which lugs 21 on the tumbler 16 project. Tumbler 19 hasprojections 22 shaped and positioned to lit in notches 7. Turning withinthe tumbler 19 is a tumbler 23 having a. groove 24 which receives lugs25 projecting from tumbler 19 and provided. with projections 26 shapedand positioned to lit the notches 9. The respective tumblers are soarranged that the projections thereon are suitably spaced to leavesullicient clearance for the reception of the plates 6 and 8 and thekeeper 2 and the respective tumblers are provided with suitablygraduated dials 27, 28, and 29.

The wall or margin of the concavity or recess 8 is sulliciently high tohouse the part 13 of the hasp and the dials so that there are noprojecting parts to be damaged by being struck by any object.

When the wards or projections on the various tumblers are in the properrelation to each other and to the notches 5, 7 and 9, the hasp can beclosed or opened and il' closed on turning the dials the hasp will besecurely locked.

Having thus described our invention, what we claim as new and desire tosecure by Letters Patent, is:

1. In a permutation hasp lock, the combination with a keeper having anaperture provided with notches at its margin, of plates attached to andspaced from the keeper which have apertures provided with notches intheir margins, a hasp, concentrically arranged independently rotatabletumblers carried by the hasp, eachv of the inner tumblers having agroove and the outer tumblers having lugs received in said grooves, theouter tumbler being provided with a groove, and lugs on the haspentering said groove, said tumblers being each shaped to conform to oneof the apertures and its notches aforei g i said and spaced from eachother to permit spaced from each other to ermit their looktheir lockingwith the respective plates and ing with the respective p ates andkeeper, keeper. and means to prevent relative displacement 15 2.
